cnnn-orncnnannn non on.v wenns` Application filed February nvcntion has to do with the alt wat/er and bottom sedimentsfrom oil obtained from wells; and it has for its general object the'provision of eiiicient means for collecting salt water and bottom sediments from crude oil.,

Other objects and practicaladvantages )of the invention will be lfully understood from the following description and claims when the same are read in connection ,with the drawings, accompanying and lforming partof this specification, in which Figure 1 is a view partlyin section and in elevation illustrative of the preierredembodiment of my .invention in use.

Figure 2 is an enlarged fragmentary section illustrative of one of the collectors compri'sed in my invention, the said collectorl be ing designed to receive and -llcld salt water and bottom sediments while permitting the upward passage of clear oil.v

Similar numeralssof referencev designate corresponding parts in both views of the My present i 30 lmaitained-in the casingv .-heaa c exea to the-Conduit an annular packing lThe casing 1 is preferably lformed in conventional manner of sections connected by couplings, and in the said casing 1 is disposed a conduit 2 made up of sections 3 and couplings 4. The con 1 by the means 'best shown in Figure' 1, the said means being Inadeup of a head 5 .fixed fo the casing 1, a

2, and longitudinalv rods 7 interposed between -and connected 'tothesaid heads 5 and 6. I would adsohave itl understood that I prefer to equip the casing-1l with a stuffing box 8 and with member 9 ofrubber or other appropriate material, the said stuling box and the rubber packing annulus receiv ing/the conduit 2. These means manifestly are adapted to, prevent oil A:trom blowing out i when my noveleleaner .is placed in aw-ell. ..v

- therefe a detail? other inthe eonduit,2. .In general the said collecteur-,fs are similar in construction, and

d description of the 'ollector illustratedln Figure2 will sullice to im art a definite understanding `ot all. By rey erence' to 'Figure 2 it 4 will be under'stod that the collectorl therein shown-.is made up o a downwardly tapered or cone-shape jhollow body 20, flanged' at itsupper end as designated by 21 for its retention in a couduit 2 'is .preferablyA is, 192e. vserial no. savez;

plingv 4: andbetween confronting end of conduit sections 3, and

ent from the lower end of thebody 20. vThe a tubular well 21 .pendbody 20 is providedn its upper portion with# a plurality of apertures 22`for the inward ,and'upward passage o nection it will be appreciated that incident to the passage of oil through the apertures 22 theglobuleswhich contain salt 'water and bottom sediments will be broken with a view to facilitating theupwar eiland promoting the precipitation of salt water and bottom sediments to the tubular well 21. At `its lower end the tubular well 2l is `provided'with ia tension 23, and hingedly connected at 24: to the lower end of the said extension 23 is a valve 25 ,on the hinged portion of which is' a pendent arm 26., The said arm`26 is opposed to a depending spring strip 27 on the l extension-.23,said spring strip 27 having for its function to yieldingly maintain the valve 25'in closed positiontand to permit opening of the said valve under the-weight of a predetermined :quantity of `salt water and bottom -sediments. Manife'stly when the valve 25 opens under the condition indigiated, the salt water and bottom sediments will be discharged back into the vconduit 2.

As before indicated a vertical series of the-upper portions of their bodies with extrerior 'screens 30 of fine' mesh. Any desired `number of' the collectors may beemployed within the purview of my inventiom'and in this connection I would have it understood that when fifteen-Tof the collectors are employed in a single conduit, for instance, the .five uppermostcollectors alone wwill .-be

equipped'gith the fine wire screen.

' 4 the pacticaluse of my .im rovement it wi lbe manifest that the `oil wil clean 'itself by passing through. the apertures 22 of the collectors/and through the'interst-ices 'of the l'screenon the upper collectors. Incident to -the said passage ofthe oil, the salt water and bottom sediments will be gatheredor `coldepending tubular eX- f oil, and in .this coni d passage of clear the upper of said collectors are provided on roo -lected in 4the wells 21 'and atfintervalsthe to colletoxfuntil the salt water and bottom M0 sediment/is finally discharged into the lower portion of the well.

A Notwithstanding the practical advantages f ascribed to my improvement, it will be manifest that the improvement as a lwhole is simple and inexpensive inv construction and is well adapted in general to withstand the usage 'to which oil well appurtenances are ordinarily subjected.

I have entered into a detailed description of` the construction and relative arrangement of partsembraced in the present and l preferred embodiment' of my invention in order to impart a full, clear and exact understanding ofthe same embodiment. I do not desire, however, to be understood as con- -ining myself to the'specific construction and relative arrangement of parts as disclosed, my invention being defined by m appended claims within the scope of which structural changes and changes inail-rangement may be made without departure from my invention. Havin described my invention,l what I claim an desire to secure by Letters Patent,

1. A crude oilV cleaner for oil Wells, com-v prising a conduit, and collectors arranged at intervals in the said' conduit, each of the said collectors having a downwardly tapered hollow body with a forarninous wall and .also

having a well pendent from the lower end of the body and .equipped with a normally closed valve yieldingly maintained in closed position and adaptedl to open under the weight of a collection of vsalt water and bottom sediment for the precipitation of said salt water and bottom sediment from the collector.

2. In a crude oil cleaner for oil wells, in

combination, Ia conduit, and collectors for salt water and bottom sediment arranged one above the other in said conduit, each of said collectors being inthe form of a hollowv body and having an apertured wall and also having apendent discharge well of tubular form and means forpermitting the escape of salt water andbottom'sediment from said well at intervals.` f

3. A collector for use in an oil well conduit, comprising a. downwardly tapered hollow body with apertures ,in its wall, and with means at its. upper end for joinder to a conduit, a well carried by said body and pendent from the lower open end thereof, and a spring pressed gravitational valve noilnally closing the lower end of the 4said we 4. A collector for usey in an oil well conduit including a downwardly tapered hollow body. open at its lower end and provided with foraminations in its wall, and a well pendent fromthe body and in communication with the lower open end thereof and having a yielding valve discharge at its lower end.

5. The combination of a .well casing, a conduit arranged in and spaced from said casing, a stuiiing box at the upper end of the casing, packing carried by the casing and engaging the conduit, and salt water and bottom sediment collectors arranged one above the other in the conduit and each having a downwardly tapered hollow body with passages in its wall and with means on its upper portion to hold it in the conduit-and also having a lower well portion and.. yielding means connected therewith adapted to discharge salt Water and bottom sediment back into the conduit. v
